DNA replication is a form of template-directed polymerization that occurs with the aid of numerous enzymes. By developing a DNA replication mimic that can undergo template-directed polymerization without enzymes, the scope of template-directed...

Precision experiments such as laser cooling and trapping using diode laser systems are increasinglyprevalent in the fields of modern atomic, molecular and optical physics. Multiple laser diodes ofprecise frequencies and significant output power are...

The frequency of a laser-diode can be locked by providing a negative feedback voltage to the piezo-electric transducer in the laser cavity. By phase-modulating the light and placing sidebands on the carrier frequency, the fluorescence of the atoms...
